After the Continuation War Finland was ordered by the USSR to provide 50 wooden sailing-motor fishing schooners as reparations. One of them was taken, and in 1952 modified, into a low magnetic research vessel named Zarya for the Pushkov Institute of Terrestrial Magnetism, Ionosphere and Radiowave Propagation (IZMIRAN).[1] From 1953 the ship was used to measure the magnetic field of the Earth. She participated in the International Geophysical Year in 1957–1958.[3]

In 1991 IZMIRAN was transferred to the Russian Academy of Sciences.

In 1976 a rupes on planet Mercury was named after the ship, the "Zarya Rupes".[4]
